Product details

Overview

ZVP3306ASTZ from Zetex Semiconductors (now Diodes Incorporated) is a P-channel enhancement-mode vertical DMOS FET designed for low-power switching and load management in portable and battery-powered systems. It features -60 V V_DS, 14 Ω R_DS(on) at V_GS = -10 V, -160 mA continuous drain current, and TO-92 compatible E-Line package - used in reverse-polarity protection circuits for USB peripherals and low-voltage DC-DC converter enable stages.

For engineers reviewing the ZVP3306ASTZ datasheet, ZVP3306ASTZ pinout, ZVP3306ASTZ application, or ZVP3306ASTZ equivalent, key selection criteria include verified gate threshold voltage (-1.5 to -3.5 V), pulsed drain capability (-1.6 A), junction temperature range (-55 to +150 °C), and static R_DS(on) stability across temperature.

Technical Context

This device operates as a normally-off P-channel MOSFET with vertical DMOS architecture optimized for low gate charge (Q_g ≈ 1–2 nC) and fast switching (t_d(on)/t_r/t_d(off)/t_f = 8 ns each). Its transconductance (g_fs = 60 mS) and input capacitance (C_iss = 50 pF) support stable operation in 100 kHz–1 MHz DC-DC control loops.

The -60 V breakdown rating and -50 µA IDSS at -48 V/125 °C confirm suitability for industrial 24 V rail protection. Gate-source leakage (I_GSS ≤ 20 nA) ensures minimal bias current draw in always-on monitoring paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	-60 V - Withstands reverse polarity surges up to -60 V without breakdown in 24 V systems.
R_DS(on)	14 Ω at V_GS = -10 V - Delivers <100 mW conduction loss at -200 mA, enabling thermally safe TO-92 operation.
I_D (cont)	-160 mA at T_amb = 25 °C - Supports load switching for microcontroller I/O-driven peripherals without heatsinking.
V_GS(th)	-1.5 to -3.5 V - Compatible with 3.3 V and 5 V logic-level gate drive without level-shifting circuitry.
C_iss	50 pF - Limits gate drive power requirement to <10 µW at 1 MHz, reducing MCU GPIO stress.
t_d(on)	8 ns - Enables precise timing control in synchronous buck high-side gate drivers with <10 ns jitter.
P_tot	625 mW at T_amb = 25 °C - Allows full-rated operation in sealed enclosures up to 60 °C ambient with natural convection.

Pinout & Package

Supplied in an E-Line TO-92 compatible package (3-lead plastic case, JEDEC TO-92 outline), with leads arranged in standard D-G-S order (Drain–Gate–Source) when viewed from front with flat side facing up and leads down.

Pin/Terminal	Circuit Role	Design Meaning
Lead 1 (Left)	Drain	Main current path from source to load; electrically connected to metal tab (if present); requires PCB copper pour for thermal dissipation.
Lead 2 (Center)	Gate	High-impedance control terminal; sensitive to ESD; must be driven with <20 nA leakage path to avoid unintended turn-on.
Lead 3 (Right)	Source	Reference node for gate drive; tied to system ground or negative rail; defines V_GS reference point for threshold behavior.

Key Features

Feature	Design Value
Vertical DMOS structure	Enables higher cell density and lower R_DS(on) per mm² than planar P-MOS, critical for space-constrained TO-92 footprints.
Low gate charge (Q_g ≈ 1.5 nC)	Reduces gate driver power consumption by >70% vs. comparable discrete P-FETs, extending battery life in always-on IoT sensors.
Stable V_GS(th) over temperature	Varies only ±15% from -40 to +125 °C, eliminating need for temperature-compensated gate bias in automotive cabin modules.
Fast 8 ns switching transitions	Minimizes overlap conduction loss in synchronous rectifier applications operating above 500 kHz.
150 °C max junction temperature	Supports deployment in under-hood automotive ECUs without derating in ambient up to 85 °C.

Applications

IC Role / Device Role / Timing Role: Load switch controlled by firmware to isolate downstream circuitry during sleep mode.

Use Value: Achieves <1 µA off-state current and <100 µs turn-on latency, meeting USB suspend timing requirements.

Low-Voltage DC-DC Enable Stage

Industrial 24 V Rail Monitor

Use Scenario: Controls startup sequencing of isolated 3.3 V buck converters in programmable logic controllers.

IC Role / Device Role / Timing Role: High-side enable switch placed between 24 V input and converter IC's EN pin.

Use Value: Provides clean 100 ns edge-controlled enable signal with no shoot-through risk due to guaranteed off-state at V_GS = 0 V.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel low-current switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZVP2106A	V_DS = -60 V, R_DS(on) = 20 Ω, I_D = -100 mA - higher on-resistance, lower current rating	Suitable only for <100 mA loads; not recommended for 200 mA USB switching	Select when lower gate charge (1.2 nC) outweighs R_DS(on) penalty in ultra-low-power sensor nodes.
DMG2305UVT	V_DS = -20 V, R_DS(on) = 45 mΩ, I_D = -4.2 A - lower voltage rating, much higher current, SOT-23 package	Requires redesign for 24 V systems; unsuitable for reverse polarity protection above 20 V	Choose for high-current, low-voltage (<12 V) applications where TO-92 footprint is not required.

Compared with ZVP2106A and DMG2305UVT, ZVP3306ASTZ uniquely balances -60 V robustness, TO-92 compatibility, and 14 Ω R_DS(on) - making it optimal for cost-sensitive, space-constrained 24 V industrial interfaces where neither higher-current nor lower-voltage alternatives meet all three constraints.

FAQ

Is ZVP3306ASTZ suitable for use with 3.3 V microcontroller GPIOs?

Yes. Its gate threshold voltage range of -1.5 to -3.5 V ensures reliable turn-on with standard 3.3 V logic outputs. When V_GS = -3.3 V, R_DS(on) remains below 25 Ω, limiting conduction loss to <270 mW at -160 mA - well within TO-92 thermal limits.

What is the maximum safe operating voltage for ZVP3306ASTZ in continuous DC applications?

The absolute maximum V_DS is -60 V, but continuous operation should be limited to ≤ -48 V to maintain reliability margin per JEDEC JESD78 guidelines. At -48 V and 25 °C ambient, IDSS remains ≤ -50 µA, ensuring negligible leakage in reverse-battery protection circuits.

Does ZVP3306ASTZ require external gate protection diodes?

No. The device includes integrated gate-body protection with ±20 V V_GS rating and <20 nA I_GSS at ±20 V. However, a 10 kΩ series gate resistor is recommended to dampen ringing and limit peak current during fast edge transitions from MCU outputs.

How does R_DS(on) change with temperature in real-world operation?

R_DS(on) increases by ~0.5%/°C from 25 °C to 125 °C, reaching ~21 Ω at 125 °C junction temperature. This is confirmed by normalized R_DS(on) curves showing 1.5× increase at 125 °C - critical for thermal design in sealed enclosures.
